To all whom it may concern:

Be it known that 1, JOHN WESLEY DICKINSON, .712, a citizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented a new and useful Improvement in Ball-Bearings, (if which the following is a specification.

This invention relates to a ball bearing which is especially adapted for heavy automobiles, electric trucksand gasolene delivery wagons where the main strain upon the bearing iallsaipon the shoulder of the rear axle for the reason that it is at this point is arranged the drive sprocket and the sprocket chain throws upon this particular part of the axle an unusual strain, especially with heavy or high speed machines using high power engines. This particular portion therefore requires spccialstrengthening in order to insure safety. I therefore employ a specially conrear end of the bearing in order to increase the bearing surface at the point mentioned.

The object of my bearing is not only to increase the resisting power against the strain put upon this point by the drive chain and sprocket wheel but a further object is to hold thetrear wheel hub in perfeet alinement at this point with the driving mechanism thereby doing away with any unnecessary wear or dangerof accident by slipping of the sprocket chain.

The invention consists in the novel features of conwhich I have shown applied to the parts just men-' tioned consists of a sleeve 13 which fits over the axle A and which is provided with suitable lubricating bores 13. The sleeve B is reduced in exterior diameter adjacent its outer end thereby forming a shoulder -B said shoulder having a'sloping face-Adjacent its rear end the sleeve B is provided with a circumferential'shoulder B which upon its opposite faces is curved, and the sleeve B is also provided adjacent Patented m o, 190 7.

that the balls C will find a bearing surfape at several points between said outer end and the shoulder B which shoulder limits inward movement of the ball cup 0 along the sleeve B, andwhile it is preferable to slide the ball cup 0 far enough toallow the ball 0 cup be slipped this far.

cups D and D these cups being arranged upon oppo site sides of the shoulder B These ball cups are provided with retaining rings D andwith balls D.

It will be obvious that the'ball cup D which bears upon the outer face of the shoulder B is slipped into position upon the sleeve B before the ball cup 0 is placed in position.

To hold the various parts in position a lock nut E is threaded into the rear end portion of the hub A and bearsupon the-ball cup D. This lock nut is re and also upon the ball cup D4 The rear endof the hub is closed by a suitable'du'st' cap G within which is fitted a suitable washer G; At the front end of the hub a split lock nut 'H is threaded into the hub and bears upon the ball cup 0. The sleeve B is held upon the spindle by the usual axle nutJ and the entire front of the hub A is closed by a dust cap K which is threaded upon the hub.

By referring to Figs. 2 and 4, it will be noted that the lock nuts H and Ediffer in size only. The lock nut E is split at E" and a set screw E works in said split portion and forces apart, when the set screw is screwed in, the two ends of the. lock nut E, thereby slightly increasingthe diameter of the lock nut and forcing its threads into binding engagement with the hub and looking it against any accidental displacement. The

screw H. I

It will be obvious from the above construction that the rear end portion of the hub A-is very strongly sprocket wheel.

Having thusfully described my invention what I claim and desire to secure by Letters Patent, is:-

A hearing of the kind described comprising a spindle, an axle, a sleeve fitting upon the spindle and,fitting upon the end portion of the axle, said sleeve being reduced in exterior diameter adjacent its outer end, and provided with a circumferential shoulder adjacent its lnner end, a ball .cup arranged upon the reduced end portion, ball cups arranged upon the sleeve and on opposite sides of the shoulder, balls in the cups, and means forlocklng sald cups in position.
